Double is a Blaze-style casino game — a colour wheel where you bet on red, black or white. In the Double game, red and black each pay 2× and white pays 14×, and every Double bet carries the same house edge. This Double calculator shows the exact odds and payout for each colour, because the Double game is provably fair with fixed probabilities. Whether you know it as Double or the Blaze Double wheel, the Double odds never change between rounds, so this Double calculator gives the true Double payout every time.
Standard 15-tile Double wheel: 7 red, 7 black, 1 white. Each tile is equally likely, so every bet has the same 6.67% edge — that single white tile is the whole house advantage.
| Bet | Tiles | Payout | Win chance | House edge |
|---|---|---|---|---|
| Red | 7 / 15 | 2× | 46.67% | 6.67% |
| Black | 7 / 15 | 2× | 46.67% | 6.67% |
| White | 1 / 15 | 14× | 6.67% | 6.67% |
Provably-fair spin. The winning tile (0–14) is derived from a SHA-256 hash of the seeds and nonce before the spin — same seeds always land the same tile, and you can't steer it.
Double game odds explained
Double (the red/black/white wheel found on crash-style crypto casinos) looks like a simple three-way bet, but the payouts hide a fixed cost. The standard wheel has 15 tiles: seven red, seven black and one white. Every tile is equally likely, so:
Because each tile is equally likely, the odds are exact and easy to verify — no combinatorics needed, just count the tiles. Red or black returns your stake doubled roughly 14 times out of every 30 spins; white is the rare 14× hit. The catch is that all three bets cost you exactly the same in the long run.
The white tile is the whole edge
Here's the key: if red or black each covered exactly half the wheel and paid 2×, the game would be break-even. But they don't — the white tile sits between them, and it's what gives the house its cut. A 2× payout on a 46.67% chance returns 0.9333 per unit; the white's 14× on a 6.67% chance returns the same 0.9333. That's a flat 6.67% house edge on every bet — noticeably steeper than dice or roulette.
Do Double systems or predictors work?
No. Each spin is independent — after five reds in a row, red is still 46.67%, not "cold". The popular tactics don't change anything:
- Martingale on red/black (double after a loss) feels safe until a losing streak plus the bet cap wipes out every small win at once.
- Chasing the white for its 14× is a 1-in-15 shot every spin, no matter how long it's been absent.
- "Signals" and predictor bots that claim to call the next color are selling a hashed, committed result they cannot see — pure marketing.
Is online Double fair?
On a provably-fair crypto casino, yes — and it's verifiable. The winning tile is committed from a hashed server seed, your client seed and a nonce before the spin, so it can be recomputed afterward and can't be altered. The Provably-fair spin tab reproduces this: it hashes the seeds and derives the tile 0–14, and the same seeds always land the same result. Fair means honest and verifiable — it does not remove the 6.67% edge, so over the long run you get back about $0.933 per $1. Only play with money you can afford to lose. 18+.
